From there, it gets less prescriptive. You might want to try a five-10 minute run with one minute walks a few times over. Or you might feel confident enough to attempt a slow-paced 20 minute run without stopping.

“For someone who has been running consistently for a few weeks, you can start to think about running for half an hour or so. That should get you to around the 5K mark – and it doesn’t matter if you walk during that,” Tashi says.

Between these runs, it’s so important to recover properly. “Stretching and foam rolling the calves, hamstrings and quads will be really key.
